Debuting on the main roster in 2002, Cena's career started off shaky, though he got more confident in his rapper gimmick, winning his first WWE Championship in 2005.

From there, Cena would go on to become a 16-time World Champion, main eventing multiple WrestleManias and transcending the industry into pop-culture, much like Hulk Hogan and The Rock before him.

But with his Hollywood career now getting bigger and bigger, the truth is, is that Cena's time in the ring is coming to an end, with the Chaingang leader appearing in just a handful of matches in 2018.

With such an iconic star, it's important for Big Match John to get a proper send-off, which leaves the WWE with a huge question.

Here are five WWE Superstars who could be the one, to retire John Cena.

#5 Daniel Bryan
